What is the difference between using @Test(expected = TypeOfException) and using try/catch when testing if a method or constructor properly returns an exception? A. They do the same thing.   B. @Test(expected = ...) is the proper way to unit test in java, and try/catch should only be used when unit testing in Python.   C. @Test(expected = ...) will give a passing test as soon as one exception of the proper type is thrown and then stop the test, but using try/catch will allow you to test many examples in the same test and will only stop after running all examples or reaching a fail() or an assert statement that fails.   D. We should never use try/catch when unit testing, otherwise we will catch the exception and then won't know

Which of the following statements about Python is true? A. Python does not support inheritance. B. Python does not support operator overloading. C. Python does not support garbage collection. D. Python supports function overloading.   Another name for an attribute of an object is: A. method B. class C. integer D. instance variable   Which of the following statements creates an object of the Rectangle class? A. myRectangle = createObject(Rectangle) B. myRectangle = createObject(Rectangle()) C. myRectangle = Rectangle() D. constructor(self) = Rectangle()

C++ Accept a package weight of zero; we'll ship it! If the user enters a weight that is less than zero, set it at zero instead. Do not display an error. If the distance is less than 500 miles, we'll ship that as well but we will charge for a full 500 miles. But if the distance is less than zero, set the distance to zero (which is really 500) and charge the user accordingly. This means that we will in fact ship your package less than ten miles (which differs from what the textbook says) but we will charge you quite a bit for that. We charge by the mile, so accept distances that are not multiples of 500 (e.g. 650 miles) and compute the fee accordingly (more than the cost for 500 miles, but less than for 1000). Fractions of miles are allowed so bring that input in as a double. For your screen shot, enter a package weight of 12.5 kg to be shipped 1310.5 miles. As always for money, the shipping charge should show exactly two digits after the decimal point. For parameters that are out of…

3. Consider how a Java program reads input from the keyboard. O O Give three methods from the Scanner class that you can use to read input from the keyboard with Scanner sc = new Scanner(System.in); Which method is used to read an integer with the scanner sc in 3a? Can you use the Scanner class to read an integer twice from the keyboard with the method you identified in 3b? If so, give the code that will allow that to happen. If not, explain what your program should do to use that word multiple times. When mixing Scanner methods in a program (i.e., calling different methods consecutively), which Scanner method will appear to read nothing from the keyboard if following another Scanner method? (If you do not know, put a question mark and move on). Consider what happens when your Java program writes output to the monitor (console). Give two methods that you can use to write output to the monitor.

Start with the code below and complete the getInt method. The method should prompt the user to enter an integer. Scan the input the user types. If the input is not an int, throw an IOException; otherwise, return the int. In the main program, invoke the getInt method, use try-catch block to catch the IOException. import java.util.*; import java.io.*; public class ReadInteger{     public static void main() {         // your code goes here     }     public static int getInt() throws IOException {         // your code goes here     } }
